expired pages security

pardon me,
i use PHP Version 4.3.10 with these settings below:

session.cache_expire 180 180
session.cache_limiter nocache nocache
session.cookie_domain no value no value
session.cookie_lifetime 0 0
session.cookie_path / /
session.cookie_secure Off Off

and i got problem with chache.. i can't expired pages immediatelly, so if goes offline, the pages still shown in browser. i already try to use:


<?
header("Expires: Thu, 01 Jan 2004 12:00:00 GMT");
header("Last-Modified: <?".gmdate("D, d M Y H:iexpired pages security")." GMT?>");
header("Cache-Control: no-store, no-cache, must-revalidate, max-age=0");
header("Cache-Control: post-check=0, pre-check=0", false);
header("Pragma: no-cache");
?>

and use:

<META HTTP-EQUIV="Expires" CONTENT="Thu, 01 Jan 2004 12:00:00 GMT">
<META HTTP-EQUIV="Last-Modified" CONTENT="<? echo "".gmdate("D, d M Y H:iexpired pages security")." GMT"; ?>">
<META HTTP-EQUIV="Cache-Control" CONTENT="no-store, no-cache, must-revalidate">
<META HTTP-EQUIV="Cache-Control" CONTENT="post-check=0, pre-check=0", false>
<META HTTP-EQUIV="Pragma" CONTENT="no-cache">

but the result is same. is there any code in php, php.ini or .htaccess that CAN 100% expired some of my pages immediatelly? i would like to use it in my form page. i need your suggestions, pls.

thx so much for your time
